BACKGROUND Intramedullary fixation of comminuted mid-shaft clavicle fractures has traditionally been employed with satisfactory clinical outcomes; however, pins with smooth surfaces may protrude from the bone and are prone to migration, while some threaded pins are difficult to remove post-operatively. The aim of this proof-of-concept study was to develop and evaluate the biomechanical strength...

The S-shaped clavicle poses a problem for intramedullary pin fixation. Stability of fracture fixation is closely related to the length of intramedullary pin engagement. This study was carried out to determine the engagement length of intramedullary pins into clavicular fractures using a small and a large pin. Seven pairs of fresh cadaveric clavicles were prepared and arranged into Group 1 and G...

The results of treatment using a locally-designed external fixator in 20 patients are presented. Open fractures were the main indications for external fixation. Pin tract infection occurred in 8 patients. Only 2 patients had unstable fixation which required removal of the device. One third of patients developed malunion exceeding 15 degrees and two thirds had joint stiffness after conversion to...

INTRODUCTION A literature review did not reveal any study investigating the results of surgical management of fractures of the proximal phalanx in elderly osteoporotic women. We present a case series of five patients. PATIENTS AND METHODS Five consecutive cases with seven fractures of the shaft/base of the proximal phalanx were retrospectively reviewed. The mean age of the study group was 72....

BACKGROUND Supracondylar distal humerus fractures are one of the most common skeletal injuries in children. The current treatment of choice in North America is closed reduction and percutaneous pin fixation. Often surgeons leave the pins exposed beneath a cast but outside the skin. Great variation exists with respect to preoperative skin preparation, and perioperative antibiotic administration....

PURPOSE To report the outcomes of modified Rush pin fixation for proximal humeral fractures. METHODS 42 men and 20 women aged 19 to 94 (mean, 64) years with 2- or 3-part proximal humeral fractures underwent reduction and fixation using the modified Rush pin technique. 11 patients died from reasons unrelated to the surgery. RESULTS Of 40 (out of 51) patients completing a subjective functiona...

Background and purpose - The quality of pin fixation of displaced supracondylar humerus fractures in children has not been assessed, and the clinical value of radiographic examinations after pin fixation is unclear. We evaluated pin configuration, quality of osteosynthesis, and outcome in 264 supracondylar fractures. The clinical significance of postoperative radiographs was analyzed. Patients ...

Two years after a quadrupled hamstring anterior cruciate ligament reconstruction using polylactic acid cross pin femoral fixation, a 32-year-old woman presented with symptoms of knee catching, locking, and stiffness. Diagnostic arthroscopy revealed a loose body in the anterior compartment of the knee which was determined to be part of the polylactic acid femoral fixation pin. The graft was inta...

background: tissue injuries may provoke neuro-hormonal response which in turn may lead to release of inflammatory cytokines. we hypothesize that block of afferent sensory pathways by infiltration of 0.5% bupivacaine in the scalp may decrease neuro-hormonal response in the neurosurgical patient. methods: after obtaining informed consent, forty asa physical statuses i, ii, or iii patients between...
